IMPROVED FRUIT-PBESEEVING BOX.

TO ALL WHOM IT MAY CONCERN:

Be it known thet'I, O. E. DOOLITTLE, of Boston, in the county ofSufi'ollr, and State of Massachusetts, have invented a. new and,improved Device for Preserving Fruit; and I do hereby declare that thefollowing is at full and exact description thereof, reference being badto the accompanying drawings, and to the letters of reference markedthereon.

Andin the drawings Figure 1 represents two boxes, oneinside of theother, 'with the lids or covers off.

Figure 2 represents theinner box placed on its side, to show theinterior thereof.

Figure 3 is n view of the reversed cover of the inner-box.

B B, figs. 1 and 2, show the inner box placed (in fig. 1) in the outerbox, with spaces left empty ulleround the sides and at the bottombetween the two boxes. D, fig b, shows the cover of the inner boxreversed, with strips of wood, E E E E, on the under side to keep thecover fast. G G, fig. 1, (dotted lines,) ore-strips ofn'ood faste ned onthe bottom of the inside of the outer box, upon which the inner boxrests. H H H, fig. 1, (dotted1ines,) are strips of Wood fastened of thesides of theinside of the outer box, to prevent the inner box fromshifting its place letereily. I I, figs. 1 and 2, are two bulk-heads orpartitions running diagonally across the inside of the inner box, witha, space between them. This space is filled with charcoal, or othersubstance absorbent of moisture. J J J J J 3 J J J J, 2, are slutsrunning diagonally across the otherwise open bottom of the inner box 13B. And I sometimes pack the cover of the inner box with rubber packing,or some other compressible substance. find I do not confine myself tothe use of charcoal, but use any substance absorbent of evaporatedmoisture.

And the operution of my device is this: I piece my absorbent substancein the space between the two bulkheads I I, and, placing the inner box13 B into the outer one, I pack. my fruit therein, and fasten down thetops of both the inner and the outer boxes. lhe moisture evaporatingfrom theiruit is absorbed by the absorbent substance deposited betweenthe bulh-heodsnnd the large body of air contained between the inner andouter boxes assists in the preservation of the fruit.

And whet l cluim herein as of my own invention, and desire to securebyLetters Patent, is-

1. The combination and arrangement of two or more boxes, the inner onebeing the containing-box, and the spuce between filled with air, andcommunicating with the inside of the containing-box by the help of slotsor apertures, when the some is used in combination with umoisture-absorbing substance contained'n'ithin the limits of theinnerbox for the purpose of preserving fruit, all substantially asdescribed.

2. In boxes for preserving or containing fruit, the placing of smoisture-absorbing substance or substances in communication with theatmosphere around the fruit, all substantially as and for the purposedescribed.
